Well, we put the current poll up on Tuesday when we heard about problems installing the KB913446 via Microsoft Update.  In 4 days, we've had over 2600 responses and the surprising result is that more than half of the respondents didn't even know about the number even though it is included at the bottom of all of the Microsoft security bulletins.  I guess Microsoft's marketing folks need to do a better job of publicizing it.  Another common theme in the responses is that the 866 number is only available from the US and Canada.  If there are similar numbers in other contries (I guess there are, see the first link below), that fact needs to be publicized, too.  I think we'll probably be mentioning the number every month on Black Tuesday since calls related to problems with patches are free (as are worm/virus-related calls according to the second link below).
